How would you pick out a parking lot? Just pick the high values? 225 - 255 which are close to black?_________________"Fuckin' Amesome" --- Joe Flacco

Sure. Or objects which are some area greater than X with the same attributes, or which intersect with X property boundaries, or are within a distance X of some object... there's a bunch of ways to extract meaning from any dataset. It's all about staring at the screen long enough that you decide what you want to do and how to do it._________________We live in an amazing, amazing world, and it's wasted on the crappiest generation of spoiled idiots. -- Louis CK

This is a presentation I'll be giving to the F&W folks in a few days. There's a lot more data and steps than I show there, but this explains the process and thinking without too much wandering off on tangents.

Another new thing I'm working on: big rasters can be used to replace some kinds of ground-based measurement.

I took a ground-layer DEM and subtracted it from a top-level canopy DEM to get canopy (rather, tree) height. I took an (already-rendered) basal area raster (technical tree stuff, expressed in ft^2/acre). The V-BAR equation takes advantage of the fact that in conifers, cubic volume in ft^3 is about 1/3 feet in height, and that due to breakage and other defect, board-feet volume is about 6 bf/ft^3. V-BAR is therefore expressed as (2)bf/ft^2. Now all we need is the acreage of the sale area. Then we do the summary statistics and calculate volume:

average BA (ft^2/ac)* V-BAR (bf/ft^2) * area (ac) = volume (bf)

This is an analysis that takes about 5 minutes at the most, if both the BA and V-BAR rasters need clipped, and less than 2 if they're already done.

Next: complete working inventory remotely by Friday.

This is gonna save us millions._________________We live in an amazing, amazing world, and it's wasted on the crappiest generation of spoiled idiots. -- Louis CK

I have not used Spatial Analysis much at all unfortunately. Most of my work deals with linear referencing._________________"Fuckin' Amesome" --- Joe Flacco
"I love watching special effects on my iPad." ---Howard Stern

This is Spatial Analyst, 3D Analyst, and raster math. I've found some supporting data for this kind of analysis, but most of it was done by hand with stereophotographs in the 70's. Current raster analysis is largely focused on pretty abstract stuff like "Clumpiness Indices" and cloud dispersion. This is a really straightforward metric basically replicating field measurements at whatever is the limiting resolution and then field-validated with a small sample to provide a correction factor, if necessary. The hardest part is gonna be writing up the results. The GIS work is pretty straightforward._________________We live in an amazing, amazing world, and it's wasted on the crappiest generation of spoiled idiots. -- Louis CK

There was a link on reddit to a summary about the ESRI Developer conference. It stated that Arc 11 would be x64 only which means anything programmed with ArcObjects would need modified into 64-bit architecture. It also seems the new programming part of the Arc suite will be ArcGIS Runtime. Also, it will finally be multi-threaded.

Hatte: "How would you explain the difference between a Small Scale and Large Scale Map?" (you dont need to answer just the next two questions) Would you say this is an easy or hard question? Should someone working in GIS know the answer to this question?_________________"Fuckin' Amesome" --- Joe Flacco

It's all about context. In the context of my work, anything done at a scale of a township or greater is large scale, at the scale of a section or smaller is small scale. Lots of grey area in there, sure, but again, it's a matter of context. A watershed analysis may cover a large area, but it's still a single watershed. Likewise, the timber volume math I've been working on can tell the standing volume of a single tree but covers 100,000 acres, because that's the size of the original raster. I just clip the bits I need._________________We live in an amazing, amazing world, and it's wasted on the crappiest generation of spoiled idiots. -- Louis CK

Hatte: I was wondering how many degrees you have. Do you have any GIS certifications such as GISP, the esri exams, or the imagery analyst certification?

I am way behind on all of these thing and need to get them started this summer. The GIS Tech and GIS Analyst jobs are going to be going away soon. There will be jobs in which you happen to use GIS._________________"Fuckin' Amesome" --- Joe Flacco
"I love watching special effects on my iPad." ---Howard Stern

I have no GIS certifications. I took a class once. I've picked the rest up as I went along. Mostly I learn stuff when I discover that I ned to know it. My degrees are in Forest Ecology and Photography. I have not bothered to get a MS yet as I don't want to be slowed down by academia._________________We live in an amazing, amazing world, and it's wasted on the crappiest generation of spoiled idiots. -- Louis CK

I should also add that I've never taken any classes in Forestry. This is another skill-set that I have learned by need rather than by formal training.

EDIT: just realized that's not true any more; I went to this class a few weeks ago._________________We live in an amazing, amazing world, and it's wasted on the crappiest generation of spoiled idiots. -- Louis CK
